I This. invention'relates to shoe used by football players orthe like; the principal object of theinstant. invention being to provide a simple, separable, adjustable cleat, the tip of which may be: renewed or adjust'ed 'longitudinally"from time to time to compensate forwearf or other modification of the tip as by damage orthe like.

Another object to provide novel means whereby to'insui'e against the tip being accidentally dislodged.

Another object is to provide such a structure whereby in the event of the tip becoming somewhat loosened in the base portion, support against lateral stress is at all times maintained.

Still other objects and advantages of the novel structure will appear in the further description thereof.

Referring now to the accompanying drawing, forming part of this application, and wherein like reference characters indicate like parts:

Figure 1 is a vertical central section, partly in elevation, of my improved cleat assembled as in use. J t

Figure 2 is a similarview of the cleat tip partly applied thereto.

Figure 3 is atop plan view of the assembled with the In Figure 1, represents the base portion of the cleatwhich is fastened to the sole of the shoe as bya plurality of nails or screws through circumferentially spaced holes 3 adjacent the outer edge thereof, and which holes are formed directly through .the tapered body of the cleat or calk rather than being through a flange formed upon such base portion as sometimes practiced; it being found that a substantially conically shaped calk throughout is the preferred type, wherein the base portion, at least, is of concaved or straight for several reasons, for example, if worn down within objectionably close proximity to the free end of the base, the tip may be removed entirely and replaced by a new one, or adjusted to a new position within the base, and one or more shimcleats "such as a: Claims. (c1. 36-59) ming washers, such as'shown at 6, may be placed uponthe base 25, and the tip returned to its position thereon and tightly screwed against said washer or washers. V

The base of the calk isconcaved externally and provided with-an'axial' bore 26 in the lower endthereof, extending approximately half the length of-the base; A smaller-bore 2''! extends downwardly from the upper end into thebase", providing a central bore communicating with the bore 26 and through which is positioned the bolt 28. The bore 26 is hexagonal in shape to ac-. commodate and fit the head 29 of the bolt and of the bolt is externally screw threaded for the reception of the tip 30 which is preferably of the proper consistency of rubber. However this tip is novel in that it is provided with an internally screw threaded sleeve 3|, securely incorporated therein, which sleeve extends downwardly materially below the base of the tip so that it is readily extendable within the bore 21 of the base of the cleat. Intermediate of the head of the bolt and bottom of the bore 26 is placed a spring washer illustrated at 32, it being only of a single convolution so as to act asl a lock washer when forced together and as a means to bias the bolt towards its withdrawal position and prevent it from extending beyond the upper end of the base 25. The object of such a construction is to insure against possible protrusion of the bolt beyond the upperend of the base 25 in the event of the tip 30 with its prevent same from turning, and the upper end sleeve 3| becoming dislodged therefrom, to avoid any possibility or danger of injury to a player by the bolt, and at the same time providing means for convenient application of another tip inasmuch as the protruding end of the sleeve 3| is readily extendable into the bore 21 for screw threaded engagement with the bolt, and when the tip is screwed home the bolt will be drawn tightly against the combination spring and lock washer 32 This tip may be provided with circumferential notchesiike those shown in Figure 3, or may have spaced holes therein for the reception of a wrench for turning it on or off as desired. From the foregoing it is evident that I have devised a practical way in which to combine with a'fixed base on the sole of a shoe an adjustable tip, and it is evident that further modifications of the device may be resorted to without departing from the spirit of the invention broadly. 7

Having thus described my invention, what I claim and desire to secure by Letters Patent, is:

1. A shoe calk comprising a base attachable to the wearing surface of a shoe sole, a tip, and means carried by the base for screw threadedly receiving the tip, said means comprising a bolt reciprocable within the base, but non-rotatable therein.

2. A shoe calk comprising a base adapted for fixed attachment to the wearing surface of a shoe sole, a tip, and screw threaded means one end of which is reciprocably but non-rotatably held in 'the' base and the other end of which is screw threadedly engaged by the tip.

3. A shoe calk comprising a non-resilient base for fixed attachment to the wearing surface of a shoe and having an opening therein, screw threaded means reciprocably but non-rotatably held within said opening, and a removable tip having screw threaded means adapted for attachment to said screw threaded means in the base.

4. A shoe calk comprising a base for fixed attachment to the wearing surface of a shoe, a tip, and screw threaded means one end of which is non-rotatably held in the base and the other end of which is screw threadedly engaged by the 5. A shoe calk comprising a rigid base adapted for non-resilient attachment to the wearing surface of a shoe sole, a tip, and screw threaded means one end of which is reciprocably but nonrotatably held in the base and the other end screw-threadedly engaged by the tip.

6. A shoe calk comprising a rigid base adapted for fixed attachment to a shoe sole, said base having an opening therein and a screw threaded member non-rotatably mounted upon said base but transversely movable thereof, in combination with a tip adapted to cooperate with said base, screw threaded means upon said tip adapted to cooperate with the screw threaded means upon the base to rigidly and removably secure the tip to the base.

'7. A shoe calk comprising a rigid base adapted for fixed attachment to a shoe sole, said base having a socket formed in one face, an opening through the top of said socket and a screw threaded member positioned in said socket and held against rotation by engagement with the walls of the socket but transversely movable thereof, in combination with a tip adapted to cooperate with said base, screw threaded 'means upon said tip adapted to cooperate with the screw threadedlmeans upon the base to rigidly and removably secure the tip to the base.
